Hi all,
You may have noticed that KX3 rev. 2.18 firmware just went to Production status
(meaning you can download it to your KX3 with one click from within KX3
Utility). The associated release notes can be found below.
Meanwhile, because we're _really_ starting to ship PX3s, I'm hoping to convince
a few of you to test yet another release of KX3 firmware (2.19) that has one
important change required for use with the PX3. Rev. 2.19 is not a very
exciting firmware release, but it does need testing, so I would be grateful for
a bit of help to ensure we didn't break anything.
If you're interested in testing KX3 rev. 2.19 tonight, please email me directly
in the next hour.
Thanks a lot!
Wayne

MCU 2.18 / DSP 1.30, 8-28-2014
New Features:
• 2-M DIRECT FREQUENCY ENTRY FROM OTHER BANDS: Range is 120-168 MHz.
Note: Sensitivity falls off as you move out of the 144-148 MHz range.
• 2-M TRANSMIT LIMITS: Normally, 2-meter transmit is limited to 144-148
MHz. This can be increased to 141-151 MHz for MARS use. The range can also be
limited to 144-146 MHz for KX3 owners outside the U.S. (see separate
instruction sheet).
• 2M/4M ANT. JACK PROVIDES OPTIONAL +5VDC DURING TRANSMIT: Many
high-band transverters and other gear can use a DC voltage of 3-12 V on the
center conductor of the antenna coax to provide T/R switching or other
functions. The KX3-2M/-4M module can now place +5VDC (+/- 0.3 V) on the antenna
jack if desired. To turn this feature on/off, locate the 2M/4M menu entry and
tap 2 (ATTN switch). The parameter will be either TXant 5V- (off) or TXant 5V+
(on). ant is displayed as a small antenna symbol.
Bug fixes:
• PL TONE FM DEVIATION ERROR: The PL tone deviation displayed in the
menu was about 40% lower than the actual deviation value in effect. Because of
this, repeater users should re-check their PL deviation setting. To do this,
locate the FM DEV menu entry, then tap 1 to switch to PL DEV. Set the value to
0.35 (kHz) the new default unless some other value is applicable.
• CW-IN-SSB IMPROVEMENT: The operators specified CW QSK delay is now
used during CW-in-SSB, even with external CW keying. (This was already working
with the internal keyer.)
• CW TIMING BUG FROM REV 1.95 CORRECTED: Element lengths with the
internal keyer were slightly too short due to a calculation error.
• KXPA100 AUTO POWER-ON WITH PX3: If a PX3 and KXPA100 are both in the
system, KXPA100 automatic power-on will now work even if the PX3 is turned on
first. (Note that at present there is no way to do automatic power-on of the
PX3 itself.)
• INCREASE IN ALLOWED TX CURRENT: Allows full-power output on some
bands where previously a drop to 5 watts had been observed (with an external
12-14 V supply).
• KX3-2M BAND-CHANGE FIX: With SLEEP enabled, a band change from 2
meters to any other band was causing the 2-m module to be left powered up
